Most solar hot water installations in the United States use indirect solar hot water systems. Indirect systems are more resistant to cold temperatures, and are better at retaining heat energy during colder winter months. However, indirect systems are also more expensive than direct systems. 

Direct solar hot water systems may work for some homeowners in the most southern parts of the country, but most U.S. residents will want to install an indirect system to avoid efficiency losses during colder parts of the year.
